Benefits of technology

[0008]An object of the present invention is to improve a fingerprint authentication function by excluding errors caused depending on detection forms as to fingerprint authentication.
[0009]An other object of the present invention is to provide a portable terminal device for which the fingerprint authentication function has been improved.
[0010]To achieve the above objects, according to the present invention, errors caused by detection forms can be excluded and the fingerprint authentication function can be improved by, when a fingerprint is detected, capturing form data representing the detection form of the fingerprint and, when inputted fingerprint data and registered fingerprint data are compared with each other, executing authentication referring to the form data.

Problems solved by technology

Therefore, when the inputted fingerprint information does not coincide with the registered fingerprint information, the fact that a person is the principal can not be confirmed.
Therefore, because a detected pattern is varied according to these forms of use, inconvenience that the authentication takes time may be expected when authentication detection rate is lowered.
Therefore, the user may feel inconvenience that the user has to pay attention to the direction of his / her finger against the fingerprint detecting unit or the direction in which the finger is placed, etc.

first embodiment

[0059]A first embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a block diagram showing an example of the configuration of a portable telephone device. FIG. 2 is a perspective view showing an example of the configuration of functional units of the portable telephone device. In FIGS. 1 and 2, the same units are given the same reference numerals. This portable telephone device is an example of a fingerprint authenticating apparatus or a portable terminal device, and the present invention is not limited to the portable telephone device.

[0060]A portable telephone device 2 is an example of an electronic apparatus or a portable terminal device that includes a fingerprint authenticating apparatus or a fingerprint authenticating apparatus. This portable telephone device 2 includes a fingerprint authenticating function that authenticates whether a person is the principal or another person using a fingerprint of the person. This fingerprint authe...

second embodiment

[0082]A second embodiment of the present invention will be described referring to FIGS. 11 and 12. FIG. 11 is a flowchart showing a process procedure of a fingerprint data registering process. FIG. 12 is a flowchart showing a process procedure of an authenticating process.

[0083]In this embodiment: the portable telephone device 2 shown in FIGS. 1 and 2 is also used; in the registering process, the flowchart shown in FIG. 5 is also used; in the authenticating process, the flowchart shown in FIGS. 8 and 9 is also used; and, in the screen process, the messages shown in FIGS. 7A and 7B are also used. Therefore, the description of each of the apparatus and the flowcharts is omitted.

[0084]In this embodiment, the fingerprint data are registered in the fingerprint data storing area 104 correlating the data with the form data and the authenticating process is executed based on the registered data.

[0085]In this fingerprint data registering process, as shown in FIG. 11, the form data representi...

third embodiment

[0089]A third embodiment of the present invention will be described referring to FIGS. 13, 14, 15, and 16. FIG. 13 shows an example of the configuration of a portable telephone device according to this embodiment. FIG. 14 is a flowchart showing a process procedure of the main routine of fingerprint data registration. FIG. 15 is a flowchart showing a process procedure of a fingerprint data registering process. FIGS. 16A, 16B, and 16C show display messages displayed on the display unit. In FIGS. 13 and 16, the same parts as those of FIGS. 1, 2, and 7 are given the same reference numerals.

[0090]As shown in FIG. 13, the portable telephone device 2 used in this embodiment is configured to capture a plurality of different forms of fingerprint data from the fingerprint sensor unit 4 in stead of the form detecting unit 6 (FIG. 1). Because other parts of the configuration are same as those of the first embodiment, the description of those parts is omitted.

[0091]In this embodiment, registrati...

Abstract

The present invention relates to finger authentication and improves a fingerprint authenticating function by excluding errors caused depending on detection forms. When a fingerprint is detected, form data representing the detection form are captured and, when inputted fingerprint data are compared with registered fingerprint data, authentication is executed referring to the form data. Thereby, the errors caused depending on the detection forms can be excluded and the fingerprint authenticating function is improved. A plurality of different detection form of fingerprint data are registered, a comparison target is selected from the fingerprint data, and the comparison target is compared with the inputted fingerprint data. Thereby, the fingerprint authenticating function is improved. To match the detection form, the apparatus may be configured to compare the registered fingerprint data with the inputted fingerprint data rotating either thereof and, thereby, similarly, the fingerprint authenticating function can be improved.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2006-58121, filed on Mar. 3, 2006, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates generally to fingerprint authentication that can be used for a portable telephone, etc., that has a fingerprint authenticating function, and more particularly to a fingerprint authenticating apparatus, a fingerprint authenticating method, a fingerprint authenticating program, and a portable terminal device that can cope with variation of relative positions of a fingerprint detecting unit and a finger to detect the fingerprint thereof.[0004]2. Description of the Related Art[0005]As portable terminal devices such as portable telephones, etc., those having a fingerprint authentication function for identifying users thereof prevail. As to s...
